Title: Container for controlled release of contents into surrounding fluid - is divided into number of cells used sequentially after seal on end cell is removed
Inventor: COHAUSZ HELGE B
IPC: C02F1/68
Filed: 1976-10-28
Abstract: A container which is divided into a number of individual cells is filled with chemicals. When the container is placed in a fluid, the chemicals are required to dissolve at a controlled rate. By removing the seal on an outside cell of the container, the process of dissolution is started. When the first cell is empty, the neighbouring cell is exposed to the surrounding fluid. This causes the seal of the cell to break, thus its content is able to dissolve and therefore mix with the surrounding fluid. Pref. both the container and the seal are made of plastics. Used e.g. controlled release of chemicals into the air to kill insects, or of chemicals into swimming bath water to kill germs etc.

Patent DE-2705930-A1 (DE)
Inventor: HARMON KENNETH BYRON
IPC: B60K17/04
Filed: 1977-02-10
Abstract: An automatic multiratio drive transmission having an automatic shift control system with a speed and throttle position pressure controlled shift valve controlling shifts between the highest drive ratio and the next lower drive ratio. When the shift valve is in the lower drive ratio position, a normal speed pressure signal increasing with increasing speed acting on the shift valve overcomes an opposing bias force controlled by throttle pressure to upshift the shift valve to the higher drive ratio position at increasing upshift speeds for increased throttle positions and provides an upshift hysteresis force decreasing with increasing throttle positions to prevent shift cycling as the highest ratio is established in a short time period and after a longer time delay period reduces the normal speed related governor pressure in an amount equal to the upshift hysteresis force at full throttle so that the downshift speed is the same as the upshift speed at the full throttle position.

One sensor is in thermal contact with the transformer oil, while the second sensor is directly or indirectly heated by the expanding liquid in a membrane (6) so that the membrane acts on the electrical switching mechanism when a predetermined, adjustable threshold value is reached. The switching mechanism can be single-pole or multi-pole and provided with working or cooperating contacts, switch-over or blocking contacts, and so connected into the protection circuit of the transformer, that load-shedding or switch-off the transformer is brought about.
Patent DE-2825032-A1 (DE)
Inventor: CERNY JOSEF DR
IPC: H04J3/16
Filed: 1978-06-07
Abstract: This system, comprising a stationary transmitter (S) and a number of portable receiving devices (E) with n voice channels uses light or infrared radiation for the time-division multiplex signal transmission without fixed pulse frame. The modulation is produced in such a manner that constant-duration interpulse periods are inserted between continuously modulated pulses or constant-duration pulses are inserted between continuously modulated interpulse periods. Additional pulses or interpulse periods are used for synchronisation. Dispensing with a constant pulse frequency provides for maximum density of pulses which are separated from one another by interpulse periods of extreme shortness. To define the pulse frame, a counter (Z), which closes the synchronisation switch (SY) when a predetermined count is reached is used at the transmitting end (S). <IMAGE>
